I went through three different custom tune companies including Innovative Diesel. Everyone one of them could not get the total program right. Either it made good power, but the shifting was horrible or vice versa. Tonys is excellent. I'm running the extreme on my truck and it makes awesome power, and nobody has come close to how smooth it shifts with his program, and he's cheaper in price than the others. Great job Tony thank you.
